Adrian Monk: They probably panicked when they shot the guard. Maybe they dropped the gun or some bloody clothes somewhere nearby. [sniffs the dog's nose]
Adrian Monk: What, what are you doing there? What-
Marty Eels: This dog has been sniffing around a sewer recently. See these sewer grates around here? The perps might have stuffed something down in there and maybe this dog saw them do it.
Adrian Monk: You gotta be kidding. He's, he's kidding, right? He's joking. The man is joking.
Marty Eels: It'll just take two minutes to check it.
Captain Stottlemeyer: Officer! Take a look in that sewer grate.
Adrian Monk: Captain. From smelling a dog. That's impossible.
Uniformed Cop: Captain! They were stuffed down the drain just like he said.
